Wazoodle lists its PUL as food safe (but I would ask for documentation). Also, Prym, the maker of Babyville PUL (which you can buy at JoAnn's) apparently will give you a product information sheet saying the BV PUL is food safe. Mostly, I think that means its phthalate, BPA and PVC free.

From my limited research another factor FDA considers are crevices in the "container" that would be hard to clean (ie a bag would have corners/crevices). But I would only worry about this, personally, if selling them.

For personal use, I'd have no problem using the 2 products I listed above. I'm not heating my food up in my bag and I'm mostly using them so I don't have to throw away a gazillion zip locs.

I've made a couple with rip stop nylon inner with a cotton outer.

Actually, just found this:
